To all whom it may concern: p

Be it known that I, ErrA H. RYoN, a citizen of the United States,residing atjWaltham, in the county of Middlesexcand State ofMassachusetts, have invented a new and: useful .Weft-Replenishing Loom,of which the following is a specification.

taken in a different position, and 1 This inventlon relates particularly.to a weft replenishing loom of the type having a movable weft carriermagazine inwhich the weft carriers are preferably arranged in groups andin which mechanism is provided for advancing successive groups of weftcarriersrto. operative position. 1

This general type of weft replenishing mechanism is shown in priorPatents Nos. 939,326; 951,659; 1,032,709 and"1,045,- 443. Such mechanismisicommonly used on dropbox looms using a plurality of shuttles, and aparticular weft carrier in theoperatively positioned group is moved totransfer position whenever the corresponding shuttle becomes active.Theimagazine is advanced to bring another group to operative positionwhenever any weft carrier in a group or a i t 26 1) positioned in thecamjgroove 27 of 'a side cam 28 mounted 'on'the usual bottomor cam shaft29. This'cam makes 1 particular ferred. I

It is the object of my present invention to weft carrier in agroupis'trans- 7 provide improvedactuating devices forthe transfer andfeeding mechanism by means 7 of which the several operations maybe performed in a reliable and accurate manner.

W1th this general ob ect in view, an 1m- .portant feature of myinvention relates to the provision of a single actuating cam and asingle lever movedflthereby, togetherwith Another feature relatesto theprovision of p sociated with the magazine, and a worm engaging therewithand movable longitudinallyf as well as angularly. The worm and a storagespring for! advaneing the magazine whenever the spring is" tensioned andY released by the control mechanism. p My invention further relatestoarrangements and combinationsof parts hereinafter 7 described and moreparticularly pointed out v in the a pended claims.

The transferrer 13 ispivoted at 15 tothe magazine frame. A de-, pending hook 16 is pivoted at17 c to the transferrer l3 and is under the control ofa weft detectingmember or feeler 18 projecting'rearwardly tointermittently engagethe'ac'tive weft carrier. 1 When the hook 161is operatively located, asshown in Fig. 1, it is positioned for engagement ,by'the headf 19 of aplunger20 slidable vertically in a fixed bearing.21.

A member 38 is pivoted to move freely 36 on its-periphery and 37 on itsouter slde surabout the of the stud 33 and is pro vided with two arms 39and 40. The arm 39 is provided wlth a sprlng plunger 41 adapted toengage one of the notches 37in" the disk 35, while the arm 40constitutes a striker adapted to engage and lift a lock ing latch 42normallyseated'in one of the notches 36. The latch 42 is mounted upon afixedpivot 43 upon which is also mounted a second or hold-back latch 44adapted to engage another one ofthe notches 36 and to prevent backwardmovement of the plate as the latch 42 is raised. A coil spring 45'positioned between portions of the latches 42 and 44 yieldingiy forceseach of the latches into engagement with the notches 36.

A vertically movable bar 46 is pivoted at 47 to the arm 39 of the member38 and is provided with a lug 48 which is at times engaged byan offsetlug 49 formed on the end'ofthe lever 23. Normally, however, the lugs areout of engagement, as is shown in Fig. 1. A rod or link 50 is pivoted atits upper end to the transferrer 13 and at its lower end extends throughan opening in the upper end of the bar 46. v A spring 51 is positionedbetween theheaded lowerv end of the rod 50 and the offset upper endofthe bar '46. The lever 23 is further provided with an upward extension52 andan adjusting screw 53 adapted to engage the -bar '46 as the lever23 is swung upward. A heavy coil springf54 encircles the stud 33 and. isconnected at one end to a collar 55 fixed to said stud and at the otherend to the angularly movable member 38.

I Having described the details of construction of my improved actuatingmechanism, I will now describe its operation. The plunger 20 and headf19are reciprocated vertically at every alternate beat of the lay, and uponweft exhaustion the hook/16 is positioned for engagement by the head 19.The transferrer is thus actuated to insert" a fresh wveft carrier andthrough the rod "50 the transferrer moves the bar 46 to bring its lug 48into the pathof the lug 49 on the lever 28, as shown in Fig. 2. As thelever 23imoves upwardly, the member 38 is moved about the axis of thestud 33 and, against thetensionof the spring 54. Such movement of themember 38 permits the spring plunger 39 to engage the next notch 37 in,notch .36. @fthe stop screw 53 in the upward extension 52 of the lever23 engages the bar '46 and the disk35 and also causes the arm40-todisengage the locking latch 42 from the As this disengagement occurs,

forcesit rearwardlyuntil the lugs-48 and .49 are disengaged, The member38jthen 7 makes a partial revolution under the influence of the spring54, advanoingthe disk 35 and beveled gear 32, and thus feedlng themagazine through the beveled pinion 31 and parts associated therewith.

As the disk 35 revolves, the latch 42 engages. the next notch 36 and thefeeding unnecessary for the magazine to'make sudden or rapid'mov'ements.

Having thus described my invention, it is' evident that changes andmodifications. can be made thereinby those skilled in the art Withoutdeparting from the spirit and scope thereof as set forth in the claims,and I do not wish to be otherwiseilimited to the details hereindisclosed, but what I claim is 2- 1; In a weft replenishing loom, a weftcarrier magazine, feeding means to advance a fresh weft carrier in saidmagazine to transfer position, transfer mechanism, a single continuouslymoving cam, andconnections through .whichsaid cam controls the movementsof bothsaid transfer mechanism and said feeding means. 1
